在行为经济学中，收入冲击操纵（金钱获得或损失的假设叙述）可以为与初级和次级商品相关的决策提供有意义的见解。迄今为止，很少有研究考察收入冲击对健康对照和使用药物的个人延迟贴现的影响，并且迄今为止还没有研究考察收入冲击对酒精需求的影响。本研究考察了通过 Amazon Mechanical Turk 招募的成年参与者样本（N = 140）中收入冲击对行为经济评估（即延迟折扣和酒精需求）的影响。样本主要是中年人、男性和白人（平均年龄 = 38.81；37.1% 女性；77.1% 白人）。参与者被随机分配到三种收入冲击叙述之一（消极、中性、积极）。他们在收入冲击叙述之前和之后完成了两个版本的 5 个选择的延迟折扣任务（100 美元和 1000 美元）以及酒精购买任务（APT）。在负收入冲击之后，在 100 美元版本的折扣任务中，对较小的即时奖励的偏好增加，并将酒精消费抑制至零（即断点）的价格降低。 APT 对价格变化的敏感性在中性和积极的收入冲击后下降，但在消极条件下却没有下降。结果复制并扩展了先前研究收入冲击对延迟贴现影响的研究结果。此外，这是第一项研究收入冲击对酒精需求影响的研究。研究结果表明，初级商品操纵（即金钱）可能会影响次级商品（即酒精）的决策。
In behavioral economics, income shock manipulations (hypothetical narratives where money is gained or lost) can provide meaningful insight into decision-making related to primary and secondary commodities. To date, few studies have examined the impact of income shock on delay discounting in healthy controls and individuals using substances, and no study to date has examined the impact of income shock on alcohol demand. This study examined the effects of income shock on behavioral economic assessments (ie, delay discounting and alcohol demand) among a sample of adult participants recruited via Amazon Mechanical Turk (N= 140). The sample was predominantly middle-aged, male, and White (mean age= 38.81; 37.1% female; 77.1% White). Participants were randomly assigned to one of three income shock narratives (negative, neutral, positive). They completed two versions of the 5-choice delay discounting task for $100 and $1,000 and an alcohol purchase task (APT) before and after the income shock narrative. Following negative income shock, preferences for smaller immediate rewards increased in the $100 version of the discounting task and decreased the price at which alcohol consumption was suppressed to zero (ie, break point). Sensitivity to price changes in the APT decreased following neutral and positive income shock but not the negative condition. Results replicate and extend prior findings examining the impact of income shock on delay discounting. Furthermore, this is the first study to study income shock effects on alcohol demand. Findings suggest that primary commodity manipulation (ie, money) can potentially impact decision-making regarding secondary commodities (ie, alcohol).
